Andrew Tabiti took a step closer to a world-title challenge but could only stumble past the experience and game Steve Cunningham.
Tabiti, Team Mayweather's cruiserweight prospect, took the 10-rounder comfortably, 97-93, 97-94, 100-90, to move to 15-0-KO12, at the T-Mobile Arena.
But with two-time world title holder 'USS' Cunningham showing all his know-how and determination, the Las Vegas local - and trainer Floyd Mayweather Sr - couldn't find a way to break his compatriot.
Thomas Dulorme was beaten by late call-up Yordenis Ugas in a rollercoaster ruck that saw them both knocked down and the former docked two points along the way to defeat.
The Puerto Rican welterweight lost a close, but unanimous decision, 94-91 93-92 93-92, with referee Vic Drakulich's decision to dock two points for low blows, ultimately proving the difference.
Dulorme, who was due to face Shawn Porter before the former world champion withdrew due to a family bereavement, made the worst possible start hitting the canvas twice in the second, Ugas' brutal right, the first a classy uppercut, leaving him chasing at least a knockdown of his own.
Dulorme did just that in the seventh as a big left hook toppled Ugas, but by then, he'd already lost a point due to supposedly low blows.
Another deduction in the 10th swung the cards firmly in Ugas' favour, with Delorme losing for the third time, just three bouts since he became one of the victims of two-weight world champion Terence Crawford in 2015.
Juan Heraldez survived a knockdown to win a surprisingly wide unanimous decision over Jose Miguel Borrego.
The Team Mayweather welterweight moved to 13-0-KO8 at the T-Mobile Arena, Las Vegas, with a 96-93, 97-92, 97-92 success but even if he was the slicker boxer, in the ninth he was trapped in a corner and floored by one of several big lefts from Mexican Borrego.
Heraldez made the count and regained his composure and was soon back to his best, smart on his feet and letting several combinations go, but even then the knockdown could easily have cost him dearly.
Borrego looked disappointed when the scores were read out and even if the winner is part of Team Mayweather and on home soil, there were even a few jeers from the growing crowd.
Local Vegas super-middleweight Kevin Newman II saw his unbeaten record shattered with a points loss against Mark Anthony Hernandez.
